‘You know teenagers under certain laws, they are accountable for their actions, especially if the act is a criminal activity when it amounts to killing innocent people,’ said Iraqi prime minister Haider al-Abadi.

Iraqi intelligence forces have alleged that the teenager worked with the Isis ‘police force’.
